Long-term clinical outcomes following surgery for spontaneous pneumothorax caused by pulmonary blebs and bullae in dogs - a multicentre (AVSTS Research Cooperative) retrospective study.

OBJECTIVES: To report the clinical characteristics and recurrence rate of spontaneous pneumothorax secondary to pulmonary blebs and bullae following surgical management in a large cohort of dogs. To explore potential risk factors for recurrence and describe outcome. MATERIALS AND METHODS: Medical records were retrospectively reviewed for cases with spontaneous pneumothorax managed surgically between 2000 and 2017. Signalment, clinical presentation, diagnostic imaging, surgery, histopathology findings and patient outcomes were recorded. Follow-up was performed via patient records and telephone contact. RESULTS: Records of 120 dogs with surgically treated pneumothorax were identified and reviewed, with 99 cases appropriate for exploratory statistical analysis. Median follow-up was 850 days (range: 9-5105 days). Two- and 5-year survival rates were 88.4% and 83.5%, respectively. There was recurrence in 14 of 99 dogs (14.1%) with adequate follow-up, with a median time to recurrence of 25 days (1-1719 days). Univariable Cox regression analysis suggested increased risk for recurrence in giant breeds (hazard ratio = 11.05, 95% confidence interval: 2.82-43.35) and with increasing bodyweight (HR = 1.04, 95% confidence interval: 1.00-1.09). Of 14 dogs with recurrence, six were euthanased, two died of causes related to pneumothorax and six underwent further treatment, of which five were resolved. CLINICAL SIGNIFICANCE: Long-term survival for dogs with surgically managed spontaneous pneumothorax was good and associated with a low risk of recurrence. Giant breed dogs and increased bodyweight were the only variables identified as possible risk factors for recurrence. The outcome for dogs with recurrence undergoing a second intervention was also favourable.

A comparison study of an elementary school-based health center: effects on health care access and use.

OBJECTIVE: To assess the effects of an elementary school-based health center (SBHC) on access to and the use of physical and mental health services by children aged 4 to 13 years. STUDY DESIGN: A retrospective cohort analysis of parent surveys from a comparable intervention (SBHC) and a comparison of urban elementary schools. INTERVENTION: Elementary SBHC services, including preventive physical health care; the care of minor short-term illnesses, injuries, and stable ongoing medical conditions, dental screenings; and mental health counseling. PARTICIPANTS: All parents of students at both schools were asked to complete a survey. Return rates on the survey were 78.3% (570/728) and 77.0% (440/571) at the intervention and comparison schools, respectively. MAIN OUTCOME MEASURES: The use of health services, access to health services, and health service satisfaction. RESULTS: Compared with respondents at comparison schools, respondents whose children had access to an SBHC had less difficulty (P = .01) receiving physical health care for their children, ie, treatment of illnesses and injuries, immunizations, and physical examinations (odds ratio, 0.66; 95% confidence interval, 0.48-0.91). Access to an SBHC was independently and significantly related to less emergency department use (odds ratio, 0.63; 95% confidence interval, 0.40-0.99; P<.05), a greater likelihood of having had a physician's visit since the school year began (odds ratio, 1.92; 95% confidence interval, 1.39-2.65; P<.01), and a greater likelihood of having had an annual dental examination (odds ratio, 1.36; 95% confidence interval, 1.01-1.83; P<.05). Measured by a 12-item scale, respondents who reported the SBHC as their most-used health service were significantly more satisfied with their service than respondents who mostly used community clinics (z=-5.21; P<.01) or hospital clinics (z=-4.03; P<.01). CONCLUSIONS: Independent of insurance status and other confounding variables, underserved minority children with SBHC access have better health care access and use than children without SBHC access, signifying that SBHCs can be an effective component of health delivery systems for these children.

Redesigning a school health workforce for a new health care environment: training school nurses as nurse practitioners.

Diminishing financial resources for school health dictate the most efficient possible deployment of the school health workforce. School nurses trained as nurse practitioners could help resolve the common problems of ready access to and appropriate use of primary care, early detection of potentially costly medical problems, and efficient use of school health staff. To determine how best to use existing resources to meet the increasingly varied and complex health care needs of children and adolescents, a pilot project was conducted in Denver from 1994 to 1996. With physician back-up and health aide support, school nurses were trained as nurse practitioners to provide in-school diagnostic and treatment services. Based on their evaluation study of this pilot project, the authors suggest ways to solve problems in role transition, including well-balanced training; clear role definition and assignment of responsibilities; appropriate back-up and mentoring support; and issues of sustaining long-term programs.

Elementary school-based health center use.

BACKGROUND: The number of school-based health centers (SBHCs) has grown from 40 in 1985 to >900 in 1996. During the 1996-1997 school year there were 914 SBHCs, 32% of which were located in elementary schools. Despite the relatively large number of elementary SBHCs in existence, SBHCs serving elementary-aged students are not adequately represented in the literature. OBJECTIVE: To analyze physical and mental primary health care utilization in a comprehensive elementary SBHC for an underserved Hispanic population. DESIGN: Retrospective analyses of services used at an elementary SBHC during the 1995-1996 school year. We describe physical and mental health services utilization provided by SBHC staff who offered a range of primary medical and mental health services. PATIENTS: The study population was predominately Hispanic, and comprised of 811 elementary school students (grades preschool through fifth) registered for SBHC use. Analyses were conducted on 591 students who used the SBHC. RESULTS: The 591 SBHC users made 2443 visits, ranging between 1 and 54 visits/individual; mean 4 visits/student. Two thirds of visits (1638) were medical provider visits, and 33% (798) were mental health provider visits. Most students (75%) saw a medical provider exclusively, 9% saw a mental health provider exclusively, and 16% of students were seen by both. Mean duration of medical provider visits +/-SD was 15 +/- 13 minutes, mean for mental health provider visits +/-SD, 37 +/- 16 minutes. Of the 3035 diagnoses, 64% were medical and 36% were mental health diagnoses. These diagnostic frequencies are grouped as follows: acute medical (31%), health maintenance (22%), depression (10%), non-Diagnostic and Statistical Manual of Mental Disorders-IV mental health diagnoses (8%), conflict disorder/emotional disturbance (8%), chronic medical (8%), academic/learning disorder (7%), anxiety disorder (3%), and other (4%). CONCLUSIONS: High rates of SBHC utilization by this population and the range of diagnoses recorded suggest health care delivered in a comprehensive, culturally-sensitive SBHC has the potential for impacting the health and well-being of underserved elementary-aged students.
