National and regional prevalence rates were calculated using adult population data (aged \u226520\u2009years) for each District Health Board region compared with a 2011 study. A subanalysis of individual\u2010level data was used to calculate age\u2010standardised rates by diagnostic category.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 1197 adults were receiving NIV giving a national rate of 32.9 per 100\u2009000; almost twice the 2011 rate (16.7 per 100\u2009000). Significant regional variations in NIV provision (4.5\u201384.2 per 100\u2009000) were observed. The most frequent indications were obesity hypoventilation syndrome (OHS) (562, 47%), obstructive pathologies (335, 28%) and neuromuscular disorders (175, 15%); all have significantly increased in prevalence since 2011. M\u0101ori and Pacific peoples were significantly overrepresented among NIV users (2.24 [95% confidence interval (CI), 1.72\u20132.93]\u00a0and 7.03 [95% CI, 5.52\u20138.94], respectively). The prevalence of NIV\u2010dependent use (&gt;15 h\/day) was 4%.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Home\u2010based NIV provision has doubled since the previous survey, reflecting increased burden from OHS and obstructive pathologies and a disproportionate disease burden among M\u0101ori and Pacific populations. The large regional variations are concerning and highlight the urgent requirement for national service specifications, education and equipment provision. Further research is needed to address access equity.<\/jats:p><\/jats:sec>","DOI":"10.1111\/imj.15960","type":"journal-article","created":{"date-parts":[[2022,11,3]],"date-time":"2022-11-03T08:51:34Z","timestamp":1667465494000},"page":"1458-1468","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Noninvasive ventilation in New Zealand: a national prevalence survey"],"prefix":"10.1111","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8613-6368","authenticated-orcid":false,"given":"Alister","family":"Neill","sequence":"first","affiliation":[{"name":"Department of Medicine University of Otago Wellington  Wellington New Zealand"},{"name":"Department of Respiratory Medicine, Wellington Regional Hospital Capital and Coast District Health Board  Wellington New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tristram R.","family":"Ingham","sequence":"additional","affiliation":[{"name":"Department of Medicine University of Otago Wellington  Wellington New Zealand"},{"name":"Foundation for Equity and Research New Zealand  Wellington New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Meredith","family":"Perry","sequence":"additional","affiliation":[{"name":"School of Physiotherapy University of Otago  Dunedin New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel","family":"Aldridge","sequence":"additional","affiliation":[{"name":"Department of Medicine University of Otago Wellington  Wellington New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James","family":"Miller","sequence":"additional","affiliation":[{"name":"Department of Medicine University of Otago Wellington  Wellington New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bernadette","family":"Jones","sequence":"additional","affiliation":[{"name":"Department of Medicine University of Otago Wellington  Wellington New Zealand"},{"name":"Foundation for Equity and Research New Zealand  Wellington New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,11,3]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/PHM.0b013e31826edcf1"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1080\/14660820500504645"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1474-4422(05)70326-4"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1445-5994.2010.02171.x"},{"key":"e_1_2_7_6_1","first-page":"722","article-title":"Guidelines for non\u2010invasive and invasive home mechanical ventilation for treatment of chronic respiratory failure \u2013 update 2017","volume":"71","author":"Windisch W","year":"2017","journal-title":"Pneumologie"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1513\/AnnalsATS.201606-454FR"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.05.00066704"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.00206311"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.4187\/respcare.03609"},{"key":"e_1_2_7_11_1","unstructured":"Love T ENSRG.Addressing unwarranted variation: literature review on methods for influencing practice 2014."},{"key":"e_1_2_7_12_1","unstructured":"Obesity [BMI >30] adjusted rate ratios [M\u0101ori vs Non\u2010M\u0101ori & Pacific vs non\u2010Pacific] (Ref: NZ Health Survey 2021) [Cited 01 Nov 2021].
