Nursing facility staff may not be properly trained to deal with behavioral symptoms of Alzheimers disease. We collected data about specialized dementia training and turnover among licensed nurses and nursing assistants in 400 nursing units in 124 Minnesota nursing facilities. Staff training may affect the retention of paraprofessional and professional nursing staff. A diversity of training methods, including workshops or seminars, films or videos, outside consultants, reading materials, training manuals, in-house experts, role playing techniques, or an orientation program for new staff, might be used to develop more effective training programs and reduce rates of nursing assistant turnover.

We propose an explanation for variation in disease outcomes based on patient adaptation to the conditions of chronic disease. We develop a model of patient adaptation using the example of Type 2 diabetes mellitus and assumptions about the process entailed in transforming self-care behaviors of compliance with treatment, compliance with glucose monitoring, and patients knowledge seeking behavior into health outcomes of glycemic control and patient satisfaction. Using data from 609 adults with diagnosed Type 2 diabetes we develop an efficiency (fitness) frontier in order to identify best practice (maximally adapted) patients and forms (archetypes) of patient inefficiency. Outcomes of frontier patients are partitioned by categories of returns to scale. Outcomes for off-frontier patients are associated with disease severity and patient archetype. The model implicates strategies for improved health outcomes based on fitness and self-care behaviors.

Recent efforts to involve patients more actively in therapeutic decisions have suggested the relevance of computer-based interventions at clinic visits. This paper presents a longitudinal, experimental study evaluating a computer-based contraceptive decision aid in Chicago and Madison family planning clinic visits. Patient interviews at three time points evaluated patient acceptance by and program impact on 949 young women. Both Chicago and Madison patients reported high acceptance. The program resulted in improved short-term knowledge and confidence in oral contraceptive (OC) efficacy for Chicago and Madison patients. In addition, compared to their control group, Madison experimental group patients had higher OC knowledge 1 year after the initial visit and a trend for fewer pregnancies (P < 0.074). Compared to their control group, a higher percent of the Chicago experimental group patients adopted OCs after stating their intention to do so at the initial visit. Exposure to the computer program had no observable impact on the number of months on the oral contraceptive for Chicago or Madison patients. Overall findings suggest the usefulness of informatics tools as a supplement to patient-provider interactions.

OBJECTIVE To examine the likelihood of a past suicide attempt for urban American Indian boys and girls, given salient risk and protective factors. METHODS Survey data from 569 urban American Indian, ages 9-15, in-school youths. Logistic regression determined probabilities of past suicide attempts. RESULTS For girls, suicidal histories were associated with substance use (risk) and positive mood (protective); probabilities ranged from 6.0% to 57.0%. For boys, probabilities for models with violence perpetration (risk), parent prosocial behavior norms (protective), and positive mood (protective) ranged from 1.0% to 38.0%. CONCLUSIONS Highlights the value of assessing both risk and protective factors for suicidal vulnerability and prioritizing prevention strategies.

We conducted a randomized controlled trial to evaluate the perception, satisfaction and utilization of a home telehealth service for frail elderly people living independently in their home communities. Control group subjects continued with their usual care and intervention group subjects were able to supplement their usual care with the use of a web portal. The web portal allowed videoconferencing and electronic messaging between home care nurses and clients, ordering health-related and home care services, access to health-related information and general access to the Internet. A total of 99 eligible people (59 female, 40 male) from one urban and one rural study site agreed to participate in the study. Eighty-four subjects were active participants for nine months. There were no significant differences in perception of technology between the two groups at baseline. At 60-day follow-up, the intervention group was significantly more positive towards technology compared to their own baseline (P < 0.001) and compared to the 60-day scores for the controls (P < 0.001). The intervention group indicated that overall the telehealth service met their expectations (mean score 9 out of 10) and they would recommend it to others (mean score 9.5 out of 10). All subjects were able to use the portal without difficulty after brief instructions from the nurses. A total of 1054 videoconferences were conducted with the intervention subjects. Fifty-six of these (5%) had to be discontinued after successful connection because of technical problems. Intervention subjects made fewer emergency department visits than control subjects, more visits to the eye doctor, fewer visits in all categories of home care utilization, and lower use of transportation services. Frail elderly people are able to adopt home telehealth technologies which may enable them to maintain independent living arrangements.

School-based clinics in St. Paul have provided comprehensive health services, including reproductive health care, for almost two decades. This study examines the effects of those clinics on the birthrates in their respective schools, using a newly developed methodology with numerous advantages over previous methods for estimating student birthrates. Confidentially matching the names of female students from school records with the names of mothers on birth records at the Department of Health provided birthrates for each of the St. Paul public high schools with clinics for each year between 1971 and 1986. The results show that birthrates fluctuated dramatically from one year to the next, but school-wide birthrates were not significantly lower in the years immediately following the opening of a clinic than in the years preceding it.

EXECUTIVE SUMMARY Advanced access is an outpatient scheduling technique that aims to provide same‐day appointment access. It is designed to reduce the time patients must wait for a scheduled appointment and to improve continuity of care by matching daily appointment supply and demand. Factors that make it difficult to sustain initial success in achieving supply‐demand balance include different practice styles of doctors, differences in panel compositions and patient preferences, and time‐varying demand patterns. This article proposes several performance measures that can help clinic directors monitor and evaluate their advanced access implementation. We also discuss strategies for sustaining advanced access in the long run.

Operating rooms (ORs) in US hospitals are costly to staff, generate about 70 % of a hospital’s revenues, and operate at a staffed-capacity utilization of 60-70 %. Many hospitals allocate blocks of OR time to individual or groups of surgeons as guaranteed allocation, who book surgeries one at a time in their blocks. The booking procedure frequently results in unused time between surgeries. Realizing that this presents an opportunity to improve OR utilization, hospitals manually reschedule surgery start times one or two days before each day of surgical operations. The purpose of rescheduling is to decrease OR staffing costs, which are determined by the number of concurrently staffed ORs. We formulate the rescheduling problem as a variant of the bin-packing problem with interrelated items, which are the surgeries performed by the same surgeon. We develop a lower bound (LB) construction algorithm and prove that the LB is at least (2/3) of the optimal staffing cost. A key feature of our approach is that we allow hospitals to have two shift lengths. Our analytical results form the basis of a branch-and-bound algorithm, which we test on data obtained from three hospitals. Experiments show that rescheduling saves significant staffing costs.

VALUE is a randomized controlled trial to evaluate the impact of a home telehealth program on the ability of frail elderly individuals to remain living independently in their own home as their self-care abilities decline. VALUE uses broadband access to provide virtual visits with a home care nurse, a Web portal for ordering assisted living services, physiological monitoring, and access to the Internet. Subjects were able to use the VALUE program technology without difficulty after a brief instruction session with the nurse

PURPOSE To examine the likelihood of weapon-carrying among urban American Indian young people, given the presence of salient risk and protective factors. METHODS The study used data from a confidential, self-report Urban Indian Youth Health Survey with 200 forced-choice items examining risk and protective factors and social, contextual, and demographic information. Between 1995 and 1998, 569 American Indian youths, aged 9-15 years, completed surveys administered in public schools and an after-school program. Using logistic regression, probability profiles compared the likelihood of weapon-carrying, given the combinations of salient risk and protective factors. RESULTS In the final models, weapon-carrying was associated significantly with one risk factor (substance use) and two protective factors (school connectedness, perceiving peers as having prosocial behavior attitudes/norms). With one risk factor and two protective factors, in various combinations in the models, the likelihood of weapon carrying ranged from 4% (with two protective factors and no risk factor in the model) to 80% of youth (with the risk factor and no protective factors in the model). Even in the presence of the risk factor, the two protective factors decreased the likelihood of weapon-carrying to 25%. CONCLUSIONS This analysis highlights the importance of protective factors in comprehensive assessments and interventions for vulnerable youth. In that the risk factor and two protective factors significantly related to weapon-carrying are amenable to intervention at both individual and population-focused levels, study findings offer a guide for prioritizing strategies for decreasing weapon-carrying among urban American Indian young people.
